Short links.
Serious control.
Create memorable links, track every click, generate QR codes, and manage your entire link ecosystem from one powerful dashboard.
Free to start. No credit card. Your links stay yours.
One link. Everything behind it.
Every link has an identity, a history, and a QR code.
4u.fyi gives every short link its own identity, analytics, QR code, controls, and history. One URL, fully managed — this preview is the real application.

A short link should be simple. Everything behind it can be powerful.
Custom Aliases

Real Analytics
Click activity, referrers, browsers, devices, and historical trends.
Instant QR Codes
Every short link becomes a QR code ready for print, packaging, presentations, and campaigns.
Complete Link Control
Edit destinations, disable links, set expiration dates, click limits, and redirect behavior.
Built for Speed
Redirects use a lightweight server path that resolves the destination directly — no full application load in between.
Analytics
Know what happens after the click.
A short URL should tell you more than where someone went.
